deleted. Download this archive containing H2OFFT and run the program. If the BIOS installation does not start, and H2OFFT closes without any message, then there is no sense to run it again. If, nevertheless, it will throw an error message, then please write what exactly it says.
Yes. You may continue. This is not a modified BIOS, so if it is installed nothing should change.

system restarted and got a blacķ screen with keyboard light on. nothing changed
It won’t shutdown even if I hold the power button. and the battery is built-in
Does it means your notebook cannot boot up now? I didn’t quite catch what happened.
I removed the power cable and pressed the button for disconnecting the battery. then it powered up normally

Sorry I was typing from my phone, now I run my laptop again, let me explain what happened:
First I run the bios you sent, and the system rebooted but It just went a black screen and keyboard light on, nothing else,
it kept that way for a long time, I had to disconnect the power and now it works normally.
If you mean while I was in windows after I press ok to start flashing then yes, it was strange not what the normal (original one) would do.
but other than that, I got nothing after reboot, just a black screen, and after I disconnected the power my laptop booted normally showing the logo, etc… no sign of bios update or flashing or anything.
If I am not clear, I can do it again and record a video of the process
OK. But let me be completely convinced by asking if it lasted about a minute or more.
This is because the BIOS should have been installed in the system running.
No need.
In windows: no maybe 30-40 seconds
after reboot: it was just a black screen and I let it for more than 4 minutes but eventually I force shut down the laptop
We can know for sure if you did the same thing with the latest version available 1.12, as I have 1.11 installed now,
So if it changed we can know for sure it flashed successfully.
Thank you for all the help <3
this time I got an error:
---------------------------
Error
---------------------------
IHISI: Extra Data communcation error in SMI!
SMI Return Code: 0x00
I tried to change the logo in the 1.11 version you sent with H20EZE (Easy BIOS Editor)
and I got the exact same error as v1.12 you sent
What in the world is extra data BTW? That’s an unanswerable question. Although I do not think that this error occurred due to the fact that this time I had to merge two BIOS files into one because I did not find a copy with the SPI chip on the network, I could be wrong. To check this, please do the normal update to 1.12 and then try to rollback to 1.11 with the archive you received from me.
Hm. And without changing the logo, can you still reproduce the situation happened in the first time?
Okay, I’ll try now
yes without editing it accepts the file and system reboot with black screen, same thing as before.
@Sweet_Kitten hmm, that’s strange,
I flashed the 1.12 stock version,
then I tried to flash the 1.11 you sent (Which was flashing and rebooting) but now It gives me the “IHISI: Extra Data communcation error in SMI! SMI Return Code: 0x00” error.
and then I tried to flash the 1.12 you sent, and it accepts it this time and I got the black screen again.
I really don’t know what is going on here 
@w4po
Now we know that it correlates in a way H2OFFT don’t proceeds if the bios has any difference to current installed. And this is probably because it verifies the identity. The BIOS is read each time by the program to determine the version. I will try to disable this.
